Description

Heat-resistant chocolate and method for producing the same

The present invention relates to a heat-resistant chocolate and a method for producing the same.

The chocolate-eating culture has developed in Europe with a cool climate. And now it is spreading to every country and region around the world. Common chocolate contains only cocoa butter contained in cacao beans as an oil and fat, and its heat resistant temperature is about 31 ° C. Therefore, it melts in a hot environment and the quality is impaired. Accordingly, there is a need for heat-resistant chocolate (hereinafter referred to as “heat-resistant chocolate”) in hot regions such as the vicinity of the equator.

Examples of methods for imparting heat resistance to chocolate include, for example, a method of blending fats and oils with a high melting point in chocolate, a method of increasing the solid content of chocolate (reducing oil content), and mixing a small amount of water with chocolate dough to make sugar. A method of forming a skeleton of The blending of fats and oils with a high melting point makes the mouthfeel of chocolate remarkably worse. The increase in the solid content of the chocolate damages the mouthfeel of the chocolate. Formation of the sugar skeleton inside the chocolate can impart heat resistance to the chocolate without damaging the mouth and mouthfeel. However, mixing a small amount of water into the chocolate dough causes an increase in viscosity and decreases productivity. Also, the heat resistance of chocolate tends to vary.

In order to suppress the increase in the viscosity of the chocolate dough, a method of mixing glycerol or sorbitol instead of water (for example, US Pat. No. 6,488,879), a method of mixing a water-in-oil emulsion (for example, US Pat. No. 6,165,540) or the like is known. . However, even with these methods, the increase in viscosity is still large, and the heat resistance tends to vary. In order to obtain excellent heat-resistant chocolate, strict process control and long-time temperature adjustment (curing) for stabilizing the sugar skeleton were required.

Hereinafter, embodiments of the present invention will be described in detail. In addition, this invention is not limited to the following embodiment.

<Chocolate>
In the present invention, the term “chocolate” is not limited by the “Fair Competition Rules for the Display of Chocolates” (National Chocolate Fair Trade Council) or the provisions of laws and regulations. If necessary, add cacao ingredients (cocoa mass, cocoa powder, etc.), dairy products, fragrances, emulsifiers, etc. to make chocolate manufacturing processes (mixing process, atomization process, scouring process, temperature adjustment process, molding process, cooling process, etc.) It refers to those that have been manufactured through part or all. Moreover, the chocolate in this invention contains white chocolate, color chocolate, etc. other than milk chocolate.

The chocolate of the present invention contains 28 to 44% by mass of fats and oils. Here, the fats and oils are not only fats and oils such as cocoa butter but also total fats and oils contained in chocolate raw materials such as cacao mass, cocoa powder, and whole fat milk powder. For example, in general, the cocoa mass has an oil (cocoa butter) content of 55% by mass (oil content 0.55), and the cocoa powder has an oil (cocoa butter) content of 11% by mass (oil content 0.11). The fat content in the whole fat powdered milk is 25% by mass (oil content 0.25), so the fat content in chocolate is the oil content in the blending amount (% by mass) in the chocolate of each raw material. It is the total value of the products multiplied by. The fat and oil content of the chocolate of the present invention is preferably 30 to 40% by mass, more preferably 31 to 39% by mass, and further preferably 32 to 38% by mass from the viewpoint of workability and flavor. .

Since chocolate has a fat and oil continuous phase, the fat content of chocolate greatly affects the viscosity. The greater the fat content, the lower the viscosity, and the effect of increased viscosity caused by the addition of water can be reduced. However, the sugar ratio is reduced, the sugar skeleton structure becomes brittle, and the heat resistance of the resulting chocolate may be reduced. On the other hand, when the oil and fat content is 30% by mass or less, the viscosity of the chocolate is increased, and the influence of the viscosity increase due to the addition of water is also increased. Therefore, the handling property at the time of chocolate manufacture may fall. However, such a reduction in handling property can be suppressed by blending an emulsifier having a viscosity-reducing action (lecithin, polyglycerin condensed ricinoleate (PGPR), etc.) into chocolate and adjusting the viscosity appropriately. The content of the emulsifier having a thinning action is preferably 0.2 to 1% by mass in the chocolate, and it is particularly preferable to use lecithin and PGPR in combination. Lecithin and PGPR are preferably used together in a mass ratio of 4: 6 to 8: 2.

The chocolate of the present invention may be either a temper type or a non-temper type. When blending a large amount of cocoa butter, it is preferably a temper type chocolate. In the case of the temper type, it is preferable that SOS type triacylglycerol (hereinafter sometimes abbreviated as SOS) is contained in the fats and oils contained in the chocolate. Here, the SOS type triacylglycerol is a triacylglycerol in which a saturated fatty acid (S) is bonded to the 1,3-position of the glycerol skeleton and oleic acid (O) is bonded to the 2-position. The saturated fatty acid (S) is preferably a saturated fatty acid having 16 or more carbon atoms, more preferably a saturated fatty acid having 16 to 22 carbon atoms, and still more preferably a saturated fatty acid having 16 to 18 carbon atoms. In the case of a temper type chocolate, the SOS content of the fats and oils contained in the chocolate is preferably 40 to 90% by mass, more preferably 50 to 90% by mass, and 60 to 90% by mass. Is more preferable.

The chocolate of the present invention contains 30 to 58% by mass of sucrose as one of saccharides. In the present invention, sucrose in chocolate is one of important components forming a sugar skeleton. As sucrose, it is appropriate to use powdered sugar obtained by powdering granulated sugar which is substantially a sucrose crystal. The sucrose content of the chocolate of the present invention is preferably 32 to 54% by mass, more preferably 34 to 50% by mass. It is preferable for the sucrose content of the chocolate to be in the above range because a sugar skeleton is easily formed in the chocolate.

The chocolate of the present invention contains 1 to 20% by mass of lactose as one of saccharides. In the present invention, lactose in chocolate is one of important components forming a sugar skeleton. Lactose is preferably crystalline and is preferably blended as lactose crystals. Most commercially available lactose is crystalline. The lactose crystals may be α-lactose or β-lactose, and α-lactose may be anhydrous or monohydrate. The lactose content of the chocolate of the present invention is preferably 2 to 18% by mass, more preferably 3 to 16% by mass, and further preferably 4 to 14% by mass. It is preferable for the lactose content of the chocolate to be in the above range since a strong sugar skeleton is easily formed in the chocolate. Whether or not lactose is crystalline can be confirmed by powder X-ray diffraction. That is, when lactose is crystalline, 2θ measured by an X-ray diffractometer (X-ray wavelength: λ = 1.5405４０) has a plurality of large peaks around 20 °, and 10.5 ° (β-type crystal). A diffraction peak is observed at 12.5 ° (α-type crystal monohydrate). It is preferable that the crystal | crystallization occupied in lactose is 60 mass% or more, and it is more preferable that it is 80 mass% or more.

The chocolate of the present invention contains 4 to 32% by mass of milk powder. The milk powder used in the present invention is not particularly limited as long as it is a milk-derived powder, and examples thereof include whole milk powder, skim milk powder, whey powder, cream powder, and butter milk powder. Although 1 type or 2 types or more can be selected and used for powdered milk, it is preferable that full-fat milk powder, skim milk powder, and whey powder are contained especially, and it is more preferable that full-fat milk powder and skim milk powder are contained. The milk powder used in the chocolate of the present invention is preferably produced by spray drying such as a spray dryer as in the above exemplified milk powder. The milk powder content of the chocolate of the present invention is preferably 8 to 28% by mass, and more preferably 12 to 24% by mass. It is preferable that the powdered milk content of the chocolate is in the above range because the flavor and shape retention of the chocolate are good.

As long as the characteristics of the present invention are not impaired, the chocolate of the present invention, in addition to the above components (oils and fats, sucrose, lactose and powdered milk), cacao mass, cocoa powder, saccharides and dairy products (milk solids) usually used in chocolate Etc.), emulsifiers, fragrances, pigments, etc., and various foods and various modifiers such as starches, gums, thermocoagulable proteins, various powders such as strawberry powder and green tea powder, etc. .

The chocolate of the present invention has a strong sugar skeleton, and therefore has excellent heat resistance. Even if the chocolate of the present invention is immersed in n-hexane at 20 ° C., for example, it preferably retains its shape for 24 hours or more. It suggests that chocolate has a strong sugar skeleton and that fats and oils are trapped in the skeleton. The chocolate of the present invention retains its shape for 72 hours or more even when immersed in n-hexane at 20 ° C. as an index of excellent heat resistance (strong sugar skeleton). More preferably, the shape is retained for 120 hours or more. Note that “retaining the shape” means a state in which more than half of the shape remains without being broken in n-hexane.

It is preferable that the chocolate of the present invention also forms a strong sugar skeleton having a load bearing stress by a rheometer of 100 g or more. Here, the load stress is measured using a rheometer. As a sample, chocolate molded to a thickness of 7 mm is used by adjusting the temperature to 34 ° C. The load resistance stress of a rheometer (for example, Sun Scientific Co., Ltd., trade name: CR-500DX) is measured under the conditions of a table moving speed of 20 mm / min, a constant depth of 3.0 mm, and a plunger diameter of 3 mm. As the load-bearing stress by the rheometer is larger, the network formation by sugar is made stronger. As for the chocolate of this invention, it is more preferable that the load-proof stress by a rheometer is 150 g or more, and it is still more preferable that it is 200 g or more. The upper limit of the load-bearing stress by the rheometer is not particularly defined, but is preferably 600 g or less, more preferably 400 g or less, in order to maintain a better mouthfeel.

<Production method of chocolate>
The chocolate of the present invention can be produced by mixing raw materials such as fats and oils, sucrose, lactose and powdered milk, atomization by roll refining, etc., and conching treatment if necessary. When performing the conching treatment, the heating in the conching treatment is preferably performed at 40 to 60 ° C. so as not to impair the flavor of the chocolate. In addition, in the manufacturing method of this invention, a process and a process are used as the same meaning.

The method for producing chocolate of the present invention includes a step of adding and dispersing water (water addition step) to the chocolate in a melt state. Here, the melt state refers to a state in which fats and oils in chocolate are melted. In the case of a temper type chocolate, whether or not the chocolate is in a melted state can be determined by confirming the omission of the chocolate after cooling and solidification. When the cooled and solidified chocolate does not escape from the mold (specifically, when the mold release rate of the chocolate dough from the mold is less than 70%), it is determined that the chocolate is in a melt state.

[Water addition process]
In the chocolate production method of the present invention, the temperature of the chocolate in the melt state in the water addition step is preferably 30 to 70 ° C., and preferably 35 to 60 ° C. in the case of a no-temper type chocolate. More preferably, it is 35 to 50 ° C. In addition, in the case of temper type chocolate, after the water addition process, when the seeding process described later is performed, it may be the same as the no temper type, but when the water addition process is performed after the tempering process or seeding process described later. Is preferably from 24 to 42 ° C, more preferably from 28 to 40 ° C, and even more preferably from 30 to 38 ° C.

The amount of water added in the water addition step may be the amount used in ordinary water-containing heat-resistant chocolate, and is not particularly limited, but is 0.1 to 5.0 mass with respect to the melted chocolate. %. When the amount of water added is 0.1% by mass or more with respect to the melted chocolate, a sugar skeleton is sufficiently formed and a chocolate having excellent heat resistance is obtained. The risk of microbial contamination can be suppressed when the amount of water added is 5.0 mass% or less with respect to the melted chocolate. The amount of water added may be 0.3 to 3.0% by mass, 0.5 to 2.5% by mass, 0.5 to 2.5% by mass with respect to the melted chocolate dough. It may be 1.5% by mass.

The melted chocolate after addition of water preferably has a water content of 0.8 to 3.5% by mass, more preferably 0.9 to 2.5% by mass. More preferably, it is 1 to 1.6% by mass. The water content of the chocolate in the final state is the same.

The water added in the water addition step may be only water, or may be a composition containing components other than water together with water (hereinafter, such a composition is referred to as “water-containing material”). Even if the amount of water added in the water addition step is the same, the viscosity increase rate of the chocolate in the melt state can change depending on the component added together with the water. Specifically, when only water or a water-containing material having a high water content (fruit juice, milk, etc.) is added, the viscosity of chocolate tends to increase rapidly. On the other hand, when a water-containing material such as a sugar solution or a protein solution is added, the viscosity tends to increase relatively slowly. If the viscosity rapidly increases, the water may not be sufficiently dispersed in the melted chocolate. Therefore, the water in the water addition step is preferably a water-containing material, particularly a sugar solution or a protein solution.

Examples of the sugar liquid include solutions such as reduced starch syrup, fructose glucose liquid sugar, and sorbitol liquid containing sugar and water such as fructose, glucose, sucrose, maltose, and oligosaccharide. Examples of the protein solution include a solution containing protein such as egg white meringue, concentrated milk, and fresh cream, and water. The content of water contained in the sugar solution or protein solution may be 10 to 90% by mass or 10 to 50% by mass with respect to the entire solution. In the water addition step, when water is added in the form of a water-containing material, the addition amount may be added so that the amount of water relative to the melted chocolate falls within the above range.

The temperature of the water and the water-containing material used in the water addition step is not particularly limited, but the temperature of the melted chocolate is about the same as the temperature of the melted chocolate to which water or a water-containing material is to be added. This is preferable in that it is easy to disperse water and water-containing material uniformly. After adding water to the melted chocolate, the water may be uniformly dispersed in the chocolate by stirring or the like.

[Cooling and solidification process]
The melted chocolate that has undergone the water addition step may be cooled and solidified, and by this step, solid chocolate can be efficiently produced from the melted state.

The method of cooling and solidification is not particularly limited, but depending on the characteristics of the chocolate product such as molding or coating on food, it is cooled and solidified by, for example, blowing cold air in a cooling tunnel or the like, contacting with a cooling plate, etc. (See, for example, “Facial Oil Handbook for Confectionery” (translated by Beeya, published in 2010, Koshobo Co., Ltd.)).

The conditions for cooling and solidification are not particularly limited as long as the melted chocolate is solidified, but may be performed at 0 to 20 ° C. (preferably 0 to 10 ° C.) for 5 to 90 minutes (preferably 10 to 60 minutes).

[Heat retention process]
In the method for producing chocolate according to the present invention, it is preferable to adopt a “heat retention step” in which the chocolate after cooling and solidification is further “heat treated”. In the heat retention treatment, the chocolate after cooling and solidification is preferably 24 to 36 ° C., more preferably 26 to 34 ° C., further preferably 28 to 32 ° C., preferably 1 to 240 hours, more preferably 6 to 144 hours. More preferably, the treatment is carried out for 12 to 96 hours. By the heat retention treatment, the formation of the sugar skeleton in the chocolate can be made stronger. In addition, the chocolate after cooling and solidification to be heat-treated is preferably 16 to 24 ° C., more preferably 18 to 22 ° C., preferably 6 to 240 hours, more preferably 12 to 192 after the cooling and solidification before the heat treatment. It may have been subjected to a time pre-aging process.

The heat-resistant chocolate of the present invention may be subjected to an aging treatment after the cooling and solidifying step or the heat retaining step. The aging treatment is preferably a treatment which is allowed to stand at 16 to 24 ° C., more preferably 18 to 22 ° C., preferably 6 to 240 hours, more preferably 12 to 192 hours.

Although the chocolate of the present invention is a chocolate having heat resistance, it is different from so-called baked chocolate, and does not require a heat treatment of 60 ° C. or higher (preferably 50 ° C. or higher).

In the method for producing chocolate of the present invention, when the chocolate of the present invention is a temper type chocolate, tempering treatment or seeding treatment may be performed either before or after the water addition step.

The tempering treatment is an operation for generating stable crystal nuclei in chocolate in a melt state. Specifically, for example, it is known as an operation in which chocolate melted at 40 to 50 ° C. is heated again to about 29 to 31 ° C. after the product temperature is lowered to about 27 to 28 ° C. The tempering treatment is preferably performed before the water addition step.

The seeding process is a process for generating stable crystal nuclei in chocolate in a melt state by using a seeding agent that functions as a crystal nucleus of stable crystals instead of the tempering process. It is the process performed in order to solidify the fats and oils in chocolate as a V-type stable crystal like.

In the method for producing chocolate according to the present invention, when seeding is performed, in order to obtain the seeding effect more efficiently, the fats and oils contained in the chocolate may contain 1,3-diethyl as part or all of SOS. Preferably stearoyl-2-oleoylglycerol (StOSt) is included. The StOSt content of the fats and oils contained in the melted chocolate before seeding of the present invention is preferably 24 to 70% by mass, more preferably 26 to 70% by mass, and 27 to 60% by mass. More preferably, it is still more preferably 30 to 55% by mass. When the StOSt content is in the above range, it is preferable because the effect of seeding can be obtained more efficiently without impairing the mouthfeel of chocolate. When the StOSt content in the chocolate is in the above range, not only is the heat obtained by cooling and solidifying the chocolate obtained sufficiently (that is, the sticky feel when the chocolate is picked up is suppressed), The resulting chocolate can have good mouthfeel and bloom resistance.

In the method for producing chocolate of the present invention, when a seeding treatment is performed, a seeding agent containing at least β-type XOX crystals is added. Here, X represents a saturated fatty acid having 16 to 22 carbon atoms, O represents oleic acid, XOX represents triacylglycerol in which oleic acid is bonded to the 2-position of glycerol and X is bonded to the 1,3-position. Indicates. XOX is preferably 1,3-dibehenyl-2-oleoylglycerol (BOB) or StOSt, and more preferably StOSt. Whether or not the XOX crystal is β-type can be confirmed by powder X-ray diffraction.

The seeding agent may be composed of β-type XOX crystals and contains other fats and oils (sunflower oil, palm olein, etc.), solids (saccharides, powdered milk, etc.), etc. in addition to β-type XOX crystals. May be. The β-type XOX crystal in the seeding agent is preferably 10% by mass or more and more preferably 30% by mass or more from the viewpoint that the effect of seeding is easily obtained. The upper limit of the amount of β-type XOX crystal in the seeding agent is not particularly limited, and is preferably 100% by mass or less. From the viewpoint of improving handling suitability and dispersibility in chocolate dough, it is preferably 50% by mass or less.

In the method for producing chocolate of the present invention, when the seeding treatment is performed, the amount of β-type XOX crystals added to the melted chocolate is 0.1 to 15% by mass with respect to the fats and oils in the chocolate. It is preferably 0.2 to 8% by mass, more preferably 0.3 to 3% by mass. When the amount of β-type XOX crystals is within the above range, even if the temperature of the melted chocolate is high (for example, 32 to 40 ° C.), even if the chocolate is held at such a high temperature, You can expect a stable seeding effect. After adding the β-type XOX crystal to the melted chocolate, the β-type XOX crystal may be uniformly dispersed in the chocolate dough by stirring or the like. In addition, XOX content in fats and oils of a seeding agent is handled as β-type XOX crystal content in fats and oils.

In the chocolate production method of the present invention, when the seeding treatment is performed, the temperature of the chocolate in the melt state is preferably 32 to 40 ° C. By maintaining the dough temperature of the chocolate dough at 32 to 40 ° C., an increase in the viscosity of the chocolate can be suppressed. The temperature of the chocolate in the melt state is preferably 34 to 39 ° C, more preferably 35 to 39 ° C, and most preferably 37 to 39 ° C. When the temperature of the chocolate in the seeding process is high, the seeding process can be performed efficiently by increasing the amount of the seeding agent containing at least β-type XOX crystals.

In the method for producing chocolate of the present invention, when the seeding treatment is performed, the seeding treatment and the water addition step are included, but any order may be used first. Moreover, you may perform a seeding agent addition and a water addition process simultaneously (that is, you may add a seeding agent and water simultaneously to melted chocolate).

The chocolate obtained from the production method according to the present invention can be eaten as it is after being subjected to the above steps. In addition, the chocolate in the present invention is used by being mixed with dough as a confectionery bakery product (for example, bread, cake, Western confectionery, baked confectionery, baked confectionery, doughnut, shoe confectionery, etc.) as a coating, filling or chip. A variety of chocolate composite foods (foods containing chocolate as a part of the raw material) can be obtained.
